1945 - with the Soviets preparing to invade Japan's northern islands, a top-secret military installation rushes to erase any sign that it ever existed.

Present day, a routine close protection assignment for former special operations soldier Ryan Mitchell and his team suddenly turns deadly. Drawn into a lethal game in which the balance of power in the world hangs in the balance, Mitchel races to stop shadowy forces and their murderous agenda before all is lost.
From war-torn Japan, to Mongolia, to Texas the fight for survival is on.
